Answer:
a
Step-by-step explanation:
a=-4 r=12/-4=-3
T7= ar^n-1
= (-4)(-3)^7-1
=-2916
The first term of this geometric sequence is equal to: A. -2916.
How to calculate the 7th term of a geometric sequence?Mathematically, a geometric sequence is given by this expression:
[tex]a_n =a_1r^{n-1}[/tex]
Where:
r is the common ratio.a is the first term of a geometric sequence.Based on the geometric sequence, the first term is equal to -4. Also, the common ratio is given by:
r = 12/-4
r = -3.
For the 7th term, we have:
a₇ = -4 × (-3)⁷⁻¹
a₇ = -4 × (-3)⁶
a₇ = -4 × 729
a₇ = -2916.

Complete the two-column proof using the answers in the bank. Given: DF ≅ EF FG bisects ∠DFE Prove: ∆DFG ≅∆EFG
Please explain the anwser, because I don't know how to do this correctly.
Answer:
Reasons:
1. Given
2. Given
3. Definition of bisector
4. Reflexive property
5. SAS Congruence
Step-by-step explanation:
This is quite easy to solve. All that you're expected to do is to complete the reason that justifies each statement given in the two-column proof.
Let's complete the proof as follows:
1. Statement: [tex] DF \cong EF [/tex]
1. Reason: Given
We know this statement is true because we are given in the question.
2. Statement: FG bisects <DFE
2. Reason: Given
We also know this because we are told so in the question, as shown in the diagram given.
3. Statement: [tex] \angle 1 \cong \angle 2 [/tex]
3. Reason: Definition of bisector
We know this because an angle bisector divides an angle into two equal halves. Therefore, the definition of bisector justifies why it was stated that [tex] \angle 1 \cong \angle 2 [/tex]
4. Statement: [tex] \overline{FG} \cong \overline{FG} [/tex]
Reason: Reflexive property.
5. Statement: ∆DFG [tex] \cong [/tex] EFG
5. Reason: SAS Congruence
Two sides (DF and FG) and an included angle (angle 1) of ∆DFG is congruent two corresponding sides (EF and FG) and an included angle (angle 2) of ∆EFG. Therefore, ∆DFG [tex] \cong [/tex] EFG by the Side-Angle-Side (SAS) Congruence Theorem.
Jonathan decides to go to an arcade  Play some games. He sets a limit of $35 that he will spend 
Answer:
Hope it will help you
Step-by-step explanation:
Option BJonathan can buy 33 games.
What is equation?The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, Jonathan decides to go to an arcade to play some games. He sets a limit of $35 that he will spend
Let he can buy x games, then the equation will be,
0.75x+10 = 35
0.75x = 25
x = 100/3 ≈ 33
Hence, Jonathan can buy 33 games.

Answer:
sin(5x)
Step-by-step explanation:
Recall that the half angle identity relates the sine of half an angle to the square root of one minus the cosine of the angle as shown below:
[tex]sin(\frac{\theta}{2} )=+/-\sqrt{\frac{1-cos(\theta)}{2} }[/tex]
therefore, in our case:
[tex]sin(5\,x )=+/-\sqrt{\frac{1-cos(10\,x)}{2} }[/tex]
so, make sure you type the expression : "sin(5x)" in the provided text-box.

Suppose it is certain that an earthquake will occur someday. What is the probability (to the nearest percent) that it will occur while you are at work? Assume you are at work 8 hours per day, 240 days per year.
Answer:
22%
Step-by-step explanation:
Given that:
Number of hours at work daily = 8 hours
Number of days at work per year = 240
Total number of hours at work per year = Number of hours at work daily [tex]\times[/tex] Number of days at work per year
Total number of hours at work per year = 8 [tex]\times[/tex] 240 = 1920 hours
Total number of days in an year = 365
Total number of hours per day = 24
Total number of hours in an year = 24 [tex]\times[/tex] 365 = 8760
Here, to find the probability that the earthquake will occur while the person is at work, we actually have to find the fraction of number of hours at work to the total number of hours in an year.
Therefore, the required probability is:
[tex]\dfrac{1920}{8760} \approx \bold{0.2191}[/tex]
Therefore the probability to the nearest percent is: 22%

6 friends all use $2 off coupons to buy themselves movie tickets. They spend a total of $42 Write the equation
Answer:
(C / n) + 2
Step-by-step explanation:
Amount spent (C) = 42
Number of friends (n) = 6
Coupon on ticket = $2
Original price of ticket will be :
Cost per coupon ticket = (Total amount spent / number of friends)
(Total amount spent / number of friends) + coupon on ticket
= (C / n) + 2
= (42 /6) + 2
= 7 + 2

The number 1.255 is an example of a terminating or repeating
decimal number?
Answer:
Terminating
Step-by-step explanation:
Since the number ends exactly after 3 decimal places, it is a terminating decimal number.
On the other hand, repeating decimal numbers are numbers such as 2.33... or 8.66... that repeat the number forever.
So, the number 1.255 is terminating.
